IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent No. 142,255, dated August 26, 1873; application filed August 5, 1873. A

' tachmentto a tub to facilitate the cleansing of clothes without rubbing with the hands.

A A are uprights, connected at the top and bottom by the cross-pieces B B, forming a frame in which are journaled two rollers that work one upon the other. The lower roller, C, is constructed of two circular disks, a and a, secured upon a shaft, and having between and in them journaled a series of polygonal wooden rolls, 1) b, which are arranged with their axes parallel to each other in the form of a cylinder of nearly equal diameter with the disks. The upper roller, D, is grooved circumferentially, and journaled at its ends in boxes (1 d, which are fitted in slots in the standards or uprights A A, the said boxes being each provided with a stem, 0, that plays through an opening in the upper cross-piece B, and serves as a guide to the boxes. Interposed between the boxes and the upper crosspiece, and inclosing the stems of the boxes,

I p are spiral springs j, which serve to keep the upper roller down upon the lower roller, but allow it to yield to adapt itself to the varying thicknesses of clothes passing between the rollers. The machine is worked by means of the crank E on the end of the shaft of roller 0.

In using, the machine is designed to be attached to a common wash-tub, and the clothes to be placed between the roller when the crank upon being turned alternately in one direction and the other, the clothes will be subjected not only to the usual squeezing action, but to a continued concussion or pounding caused by the action of the polygonal rollers.

This machine possesses, in an eminent degree three essential elements of agood washing-machine, viz: Friction, pressure, and concussion. The lower roller being composed of polygonal rolls, each of which has an independent movement, a greater amount of friction is produced than by cylinders composed of round rolls. The lower roller being composed of independent rolls, each roll thereof acts asa pounder. The shape of the rolls results in carrying the materials under the pressure-roller, instead of drawing or pulling them under, as is the case with solid rollers or rollers composed of round rolls, thereby preventing the clothes from stretching, or being torn, or in anywise injuring or interfering with buttons, buckles, 8pc. It is also easier to operate than most machines of this kind on account of its requiring less power to carry materials under the pressure roller than it does to drag or pull them under. By employing a grooved pressure-roller we thereby prevent the materials from pushing or sliding to one side, thus securin g a uniform distribution of the clothes, and at the same time retain all the necessary pressure to secure good wash- Having thus described our invention, what we claim as new, and desire to secure by Let ters Patent, is-- The washing attachment described, consisting of the frame A A B B, rollers G D, boxes d d, with stems and inclosing springs e f, all constructed as set forth.
